Problem with S32K148 and DP83848

[Zhangfeng1]

I am testing a controller board, whose main chip is S32K148 and network chip is DP83848. If I want to run the LWIP protocol stack, what parts do I need to modify on the official example? What other options may need to be modified besides modifying the MII option in the tcpip component when I use RMII for communication? The circuit of DP83848 has been verified on another controller and there is no problem.

Looking forward to your reply, thank you.

Hi,

per my understanding no further setting would be needed. You can just check pin initialization if it corresponds to your connection.
No PHY init is done in demo, I think. PHY can be configured via strap options to run in some mode, and if it is the same with the option selected in tcpip component, no PHY init is required.
